🟣 METADATA_OPERATOR

RTT/1 Operator Specification — archive_org Module#

Identity#

  • Operator Name: METADATA_OPERATOR
  • Operator Family: R‑Ops (Registry / Root Operators)
  • Module: archive_org
  • Purpose: Normalize Internet Archive metadata into RTT grammar to determine substrate, regime, drift sensitivity, coherence, and lineage identifiers.

Purpose (One Sentence)#

The METADATA_OPERATOR extracts and normalizes IA metadata to identify the object’s substrate type, regime, drift sensitivity, coherence, and lineage identifiers before any temporal analysis occurs.

Inputs#

Input Type Description
target URL The webpage or object whose metadata is being analyzed.

Outputs#

Output Description
substrate_type The structural substrate (html, pdf, image, mixed, etc.).
regime The object’s operational regime (institutional, media, scholarly, cultural, etc.).
drift_sensitivity Expected drift level based on substrate + regime.
coherence Internal structural consistency of the object.
lineage_ids Identifiers linking the object to collections, clusters, or prior versions.

Operator Guarantees#

  • No content‑based inference.
  • Metadata is treated as structural hints, not ground truth.
  • Drift sensitivity is predictive, not retrospective.
  • Regime classification is structural, not semantic.
  • Output is deterministic given the same IA metadata.

Substrate Types (RTT/1)#

Substrate Notes
html Drift‑prone, layout‑dependent.
pdf Stable, low drift.
image Stable but incomplete.
ocr Lossy, high drift.
mixed Requires PRESERVATION_OPERATOR to resolve.

Regime Types#

Regime Meaning
institutional Government, agency, or official records.
media News, blogs, high‑update environments.
scholarly Academic, research, journals.
cultural Museums, exhibits, archives.
technical Software, documentation, versioned systems.

Drift Sensitivity Levels#

Level Meaning
low Expected stability (PDF, institutional).
medium Occasional structural change.
high Frequent redesigns, CMS migrations.

Coherence Levels#

Level Meaning
high Strong structural consistency.
medium Some inconsistencies.
low Fragmented or unstable structure.

Operator Procedure#

  1. Retrieve IA metadata for target.
  2. Normalize fields into RTT grammar:
    • substrate
    • regime
    • drift_sensitivity
    • coherence
    • lineage identifiers
  3. Validate substrate classification.
  4. Predict drift sensitivity based on substrate + regime.
  5. Emit normalized metadata for WAYBACK_OPERATOR and LINEAGE_OPERATOR.

Failure Modes#

  • Missing metadata: return null fields + warning.
  • Ambiguous substrate: mark as mixed and defer to PRESERVATION_OPERATOR.
  • Contradictory metadata: flag for drift‑bounded review.

Hand‑Off to Next Operator#

Outputs feed directly into:

WAYBACK_OPERATOR#

  • substrate_type
  • drift_sensitivity

LINEAGE_OPERATOR#

  • regime
  • coherence
  • lineage_ids

Example (Synthetic)#

Input:
  target = "https://example.gov/records"

Output:
  substrate_type = "html"
  regime = "institutional"
  drift_sensitivity = "low"
  coherence = "high"
  lineage_ids = ["govdocs-root"]

RTT/1 Mindset#

  • Metadata is structural, not semantic.
  • Drift sensitivity is predictive, not retrospective.
  • Regime classification informs expectations, not conclusions.
  • Metadata never overrides observed drift.
